This invention relates to a shoe heel clamp, and has for the primary object the provision of a device of this character which is especially constructed for securing a heel in place on an outer sole of a shoe while the latter is in the course of construction on a last and which may be readily adjusted and eliminates the common practice of securing the heel in place by a screw extending through the heel, inner sole and into the last and which requires the drilling of the last to receive the screw and a machine for the tightening of the screw, consequently providing a timev and labor saving device wherein the heel will be firmly held in place while the glue which is employed for the securing of the heel and .inner sole together dries.

With these and other objects in view, the in-` vention consists in certain novel features of construction, combination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to be had to the following description and accompanying drawing, in which Figure l is a side elevation illustrating a shoe clamp constructed in accordance with my invention and showing the same adapted to a shoe heel and last.

Figure 2 is a perspective View illustrating the clamp.

Figure 3 is a detail sectional View showing a portion of the clamp and the part which engages with the tread face of the heel.

Referring in detail to the drawing, the numeral 5 indicates a block of substantially rectangular shape and has extending from end to end thereof a tie bolt l being equipped with heads l. The tie bolt secures onto opposite ends of the block elongated protecting straps 8 and also coil springs t, one of which has secured thereto one end of a strap I0, the other end portion of the strap being provided with a series of openings il to permit a buckle or similar fastener I2 to be adjustably secured on the strap and to which the other coil spring 9 is connected. The protecting straps 8 adjacent their free ends are provided with slots I3 through which the strap i0 is laced, as clearly shown in Figure 2.

The block 5 has an opening Ill to permit a finger ring I5 to extend through the block and engage with the tie bolt and thereby become anchored to the bolt.

It is customary in the construction of shoes to glue a shoe heel I6 onto an outer sole while 0n a last Il in the making of the shoe. It has been the present practice of passing a screw through the heel and outer sole and into an opening drilled in the last for securing the heel in place during the period of time of the drying of the glue and in some instances it has been necessary 5 to drive nails through the heel into the last. Through the use of the present invention the use of screws and like fasteners is entirely eliminated also machines necessary for turning the screws vtightly in place, consequently the present invention provides a time and labor saving device.

In operation, after the placing of the heel on the outer sole while on the last for thepurpose of the glue drying, the block 5 has one face thereof brought into engagement with the tread face of the heel with the protecting straps extending at opposite sides of the heel and terminating at opposite sides of the last. The strap Il) is passed about the last, as shown in Figure l, and the springs being under tension draws the block tightly against the heel forcing the latter intol tight engagement with the inner sole so that no chance of the heel -moving will be had during the time of the drying of the glue. Through the use of the coil springs 9 the device is kept taut while placed on the heel and last and through the use of the buckle or similar fastener l2 the strap may be adjusted so that the device may be successfully used in connection with heels of different sizes or heights. It is preferable that the block 5 be constructed of rubber or some similar material so as not to mar or damage the heel. The linger ring I5 provides a convenient medium for the handling and placing of the block on the heel and also may be employed for hanging the device on a support when not in use.

It is believed that the foregoing description, when taken in connection with the drawings will fully set forth the construction and advantages of this invention to those skilled in the art to which such a device relates, so that further detailed description will not be required` What I claim is:

1. In a device ofthe character set forth, a block to engage with a tread face of a heel, coil springs connected to opposite ends of said block, a last encircling strap having one end connected to one of said coil springs and its opposite end adjustably connected to the other coil spring.

2. In a device of the character set forth, a block to engage with a tread face of a heel, coil springs connected to opposite ends of said block, a last encircling strap having one `end connected to one of said coil springs and its opposite end adjustably connected to the other coil spring, and

protective straps secured to the ends cf the block and lying between the shoe heel and the springs and portions ofthe last encircling strap.

3. In a device of the character set forth, a block to engage with a tread face of a heel, coil springs connected to opposite ends of said block, la last encircling strap having one end connected to one of said coil springs and its opposite end adjustably connected to the other coil spring, and protective straps secured to the ends of the block and lying between the shoe heel and the springs and portions of the last encircling strap, said protective straps having slots with the last encircling strap laced therethrough.

Straps having slots with the last encircling strap 10 laced therethrough, and a nger ring connected to the block.
